specification, reference being had therein to the accompanying drawing. 7

This invention relates to ventilators, and

- more particularly to window sash ventilators.

and it has for. its object the provision of means for facilitating the operation of the ventilator.

Another object of this invention is the production of a ventilator which is simple in construction, and consists of a minimum number of parts.

Still another object of this invention is the production of a ventilator which constitutes a hingedgate, and which can be automatically locked in an open orclosed position.

With these'and other objects in view, this invention consists of certain novel constructions, combinations, and arrangements: of parts, as will be hereinafter fully described and claimed.

Inthe drawings: Figure '1 is a plan view of the ventilator in connection with a window sash. Fig. 2 is a sectional view taken on line 2-2, Fig. 1, looking in the direction of the arrow. Fig. 3 is a detail perspective of the angle member which connects with the door or gate. Fig. 4 is an enlarged view of the locking mechanism for the vertical rod.

Referring to the drawings by numerals, 1 designates a sash which is provided with a front opening 2, which opening 2 acts as a ventilating means. The opening 2 is provided with an outwardly-extending member 3, to the outer end of which is hinged a gate or door 4. At the junction of the member 3 and the gate 4, the edges of said member 3 and gate 4 are beveled,as at 4, so as to form a tight joint when the gate 4 is in a closed position. The top of the frame is provided with a notched portion4 in whichis adapted to fit the upper edge of the hinged gate 4, thereby forming a tight joint between the upper edge of the frame and the hinged gate or door 4.

Secured to the ate 4 is an angle member 5, which is provided with an inwardlye tending portion 5 The lower end of said inwardly-extending portion is bifurcated, as at catcd end 6 of the angle member 5.

6, and an aperture 7 is formed near the end of said inwardly-extending portion.

An angle bracket 8 is secured to the sash 1, and the outwardly-extending flanged portion is provided with an aperture 9. A vertical rodlO passes through said aperture, and said rod is bentoutwardly near its upper end and terminates into an eye 11, and said eye 11 passes through the aperture 7 and the bifur+ B being. so secured to the lower end of said gngle member 5, it will be seen that the rod 10 will be held in a set osition against rotation. The inner side of the rod 10 is provided with teeth 12, which teeth are adapted to engage the side of the aperture 9 of the angle bracket 8. Secured to the sash 1 is a fiat s ring 13, and said flat spring is provided wit an outwardly flanged portion 14. The rod 10 passes through this aperture and the urpose of the spring 13 isv to normally hold t e teeth 12 of the rod 10 in engagement with the edge of the aperture 9 of the bracket 8.

It can be readily seen that by slightly pulling the rod 10 outwardly the spring 13 will yield and disengage the teeth 12 upon the rod 10 from the edge of the aperture 9 of the bracket 8 and allow the rod to freely move up or down, so as to open or close the gate or door 4. Therefore, it will be seen that I have provided a device by which a ventilating door can be opened or shut, and be automatically locked in such a position.

' What I claim is:.

1. In a device of the class described, the combination with a Window sash, said sash provided with an' opening, of a gate or door hinged to the bottom of said opening, an angle member secured to said door, one portion of said angle member projecting below saiddoor, a verticalrod connected to the lowerend of said angle member, and means positioned upon the sash and engaging said vertical rod for locking said hinged door or gate inan open or closed position.

2. In a device of theclass described, the combination with a window sash, of an apertured angle bracket constituting a guide, a rod passing through said a erture in said angle bracket, said rod provi ed, on one side, With teeth, said teeth adapted to enga e the sides of the aperture in said an le brac 'et, a flat spring secured to said sas and terminating at its lower end into an outwardlyextending portion, said outwardly-extending portion provided with an aperture, said rod passing through said aperture, and said fiat spring constituting means for normally holding said teeth upon said rod in engagement with the sides of said aperture in said angle bracket.

v3. In a device of the class described, the combination with a window ventilator, of an operating rod, an angle-bracket, said angle bracket provided with an aperture, teeth formed upon said rod, and means passing around said rod and secured to a support for normally holding said teeth in engagement with the side of said aperture.

4. In a device of the character described, the combination with a window sash, said sash provided with an opening near one end, an outwardly extending portion secured at its inner end to one side of said opening, and said portion provided with an outer beveled edge, a swinging door provided with a lower beveled edge, means interposed between the beveled edges of the hinged gate or door and the outwardly extending portion, for hinging the same together so as to form a tight joint, and means secured to said door for manually operating the same and locking said door in an open or closed position.

5. In a device of the character described, the combination with a window frame, a slidable sash positioned in said frame, said frame provided with a notch formed along the inner edge of the top thereof, said sash provided with an opening near one end, and

groove or notch formed in the edge of said frame, and means secured to said door for manually operating the same and locking said door in an open or closed position.

6. In a device of the character described,

the combination with a window sash provided with an opening near one end, an outwardly extending portion secured at its inner end to the bottom of said opening, a door hinged to the outer edge of said outwardly extending portion, an angle member secured at one end to said hinged door by means of screws passing through apertures formed therein, said angle member provided with a downwardly extending portion, said downwardly extending portion provided with a lower bifurcated end and a transverse aperture formed directly in the rear of said bifurcation, and means passing through said aperture and having one end positioned in said bifurcated end for actuating said angle memher, for opening or closing said door.

In testimony whereof I hereunto allix my signature in presence of two witnesses.
